A macroscopic view of Enteromorpha and Ulva photographed
in Stillwater Cove at Pebble Beach, CA. Enteromorpha, as well
as Ulva, can often be found covering areas along the coast
with green beauty.
A closer view of Enteromorpha, this photo
was taken on Fisher Beach at the Hopkins Marine Station, in Pacific
Grove, CA. It is possible to distinguish the individual fronds in this
An even closer view of the surface of Enteromorpha,
this time through a microscope. The tube that Enteromorpha grows
in has been split and folded flat, so this piece of Enteromorpha is
only one cell layer thick.
Now closer still, it is possible to distinguish individual
The chloroplasts are now discernable in the individual
cells, they are the greenish opaque parts of each cell.
The chloroplasts can be seen more clearly, and one
can see that all of the cells are aligned in the same general direction.
This is the end of the exciting experience of entering Enteromorpha.
